/**
 * A map modelled after the Java HashMap, but with TypeScript semantics. There are no views for keys, values, or
 * entries that can be altered and affect the map.
 * What's different is that keys can be any type, including objects. If an object is used as a key and implements the
 * IEquatable interface, then the equals() method is used to compare keys. Otherwise the === operator is used.
